feature request: isa operator

Hi all. After using the recent template object features I've noticed the lack of an isa operator. I realize that some may see this as a slippery slope so I offer the following rather gently. The only need I have for an isa operator is to allow my templates to determine if they support a given object: {if $BLOCK isa PageBlock} The PageBlock interface is supported. {/if} The supported syntax is: {if var isa [not] type} where: var - reference to a template variable type - either 'Object' or a classname I had to patch the Smarty class to add a generic is_a function to support PHP < 4.2. The changes in Smarty_Compiler follow the existing _is* code. This patch was made against the June 10th CVS. My apologies if I made the patch incorrectly -- but it seems to work for me :) xo boots __________________________________ Do you Yahoo!? SBC Yahoo!
